North Korea announced Tuesday it has elevated an Army general named Hyon Yong-chol to the post of vice marshal, the latest move in a military reshuffle that has cast an air of uncertainty over the regime.
The promotion came a day after the sudden dismissal of former vice marshal and regime heavyweight Ri Yong-ho, a move Pyongyang chalked up to illness but that some said could be a purge to bolster the power base of young leader Kim Jong-un.
